ProteinChip Calibration Standards

To help ensure accurate profiling and quantitation, a variety of standards and calibrants are available for use with the ProteinChip SELDI system:

• ProteinChip all-in-one peptide standard — ensures accurate peptide mass assignments; includes vasopressin (human Arg8; 1.08 kD), somatostatin (human; 1.64 kD), dynorphin (porcine; 2.15 kD), ACTH (1–24; human; 2.93 kD), insulin β-chain (bovine; 3.50 kD), insulin (human; 5.81 kD), and recombinant hirudin (6.96 kD)
• ProteinChip all-in-one protein standard II — ensures accurate protein mass assignments; includes recombinant hirudin (7.0 kD), cytochrome C (bovine; 12.2 kD), myoglobin (equine; 17.0 kD), carbonic anhydrase (bovine red blood cells; 29.0 kD), enolase (S. cerevisiae; 46.7 kD), albumin (bovine; 66.4 kD), and IgG (bovine; 147.3 kD)
• ProteinChip peptide calibrant kit — includes 7 peptide standards packaged in separate tubes (2 of each standard: 1 nmol each of human angiotensin I, [human Glu¹]–fibrinopeptide B, porcine dynorphin A (209–225), human ACTH (1–24), human β-endorphin (61–91), bovine insulin, and bovine ubiquitin)
• ProteinChip protein calibrant kit — includes 10 lyophilized protein standards packaged in separate tubes (2 of each standard: 1 nmol each of bovine insulin, ubiquitin, cytochrome C, β-lactoglobulin A, superoxide dismutase, and equine myoglobin; 2 nmol each of horseradish peroxidase, bovine serum albumin, and chicken conalbumin; and 5 nmol bovine IgG)
• ProteinChip human serum control — used as a standard in serum profiling studies
